Ok, I've been racking my brains at this for a while now and can't seem to figure out why this won't fold back up. The teeth don't have to be in any specific order I was shooting for 1.020" between each but at this point it just needs to fold. It will not refold back up. I can't seem to figure it out. The edge that I used to unfold is still there, and I collected all bends but it just will not fold back up. So I figured I would post this here to see what someone else may come up with. It seems like its a bug in SolidWorks to me, but not certain. Any advice or help would be greatly appreciated.
